[0 all whom, it may comm:

a citizen the United States, unrl resident of Scranton, Luclniwunna county, State of Pennsylvania, have invented certain new and useful Improvements in Type-Kiting lllachines, or which the following is u specificetion.

The object of the present invention is to produce a type bur joint of strong and simple construction and which will permit the type bar to more with very little friction.

The invention will he described in cor tion with the ecc'onipunying drawirg, which,

Figure 7 is-a side View of u type her and hunger illustrating one form of the invention; Fig. 2 is a section on the line 2-2 of Fig. 1; 3 is a side View of the hunger shown in Fig. 1; Fig. -l is a. side View of :1 portion of the type her; Figs. 5 and ti illustre-te different forms of the invention: Fig. 7 is aperspective View of the hearing shown in Fig. 6; Fig. 8 is a section on the line 8-8 of Fi 6.

Referring to the drawing, '1 indicates a type bar and 2 a. type bar hunger. The type bar illustrated is adapted for in connection with a front strike typewriter, but in; invention is adapted for use in my type of machine. The type bur bearing illustrated in Figs. 1 to 4i comprises e polygonal block 3 having its angles or corners roundecl, us at 4, end having a cent-rel perforation through which a screw 5 passes to'cluinp the block to the hanger. The type our 1 hes a circular opening 6 in which the polygonal block 3 has a working fit. The screw 5 has annular shoulder 7 which bears upon the block 3 and clumps it securely to the hunger and an annular flange 8 which bears lightly upon the type her to hold it in place upon the bearing block 3 and prevent. vibration.

hen the parts are assembled. as shown in Fig.2, the type bur is carried upon the rounded angles or corners of the. hearing block 3 and it is guided hi; the face of the hanger and the flange 8 of the screw A bar so mounted will be found to operate with a. very little friction. The recesses netwecn the well of the eye 6 and hlccl; 3 form receptacles for lubricant and the an nular recess between the shoulder 't and the nation ofzi' type her hanger, a block connech ed with the hanger and. having a plureli flange 8 of the screw may also he clepeiuied upon to carry a portion of luh The hearing bloc i i forms. the chief sents ii ilureiity of which the type is carried. 1 the faces 9 of the block ere conca re but the corners 1t) ore rounded and present the same hearing surface to the type her the con ners of the block 3. j

In Figs. 6 and 7 have shown snot} form of the invention. Referring figures. 11 indicates it round or cylinti' bearing block which is threaded and n. ed to fit ti 'htly threaded a: ertn in the hanger 13. The block 11 is n l. with a plurality oi 'projections 1 out; surfaces of which are round and adapted to fit the eye 6 of the type her. As shown Fig. 8 the type bar mount-en on the projections l4. and is held in place h ii screw 5 having 2111 annular flange 8 anti shoulder 7 similar to the screw illustrated. inFig'. 2. The shoulder 7 hears upon the projections 14 and the flange 8 serves to holcl the type her on its hearing" and guide it. The n ject-ions 14: correspond to the corners i the polygcnelibioelr 3 and in the claims l forms of hearing will he referred to he? ing rouncletl corners or angles.

It will be noted that in each of the forms of the invention shown in the drawing hearing member is (letachahly con ects with the hanger. lit is therefore renew a worn out or defective heerii a mininuun of trouble and expense.

Having clescrihecl myinvention whet claim an"? desire to secure by Letters Pet-- ent is i 1. In a typewriting machine, the combiof integral roundecl heering surfaces spa-c one from the other. 2. type bur having culnr eye in which said hearing surf. luwen working fit, enci a screw ?4)I1Z1@"L with the hunger having flange for guiding suit type 4 2. in a typewriting' machine, the com nation with hanger. of a polygonal l'hf ing block having. rounded corners, a screw connecting said hearing lock with the hanger, and a, type her mounte onsutd W Y v benrlng Stll'filCGS, a type bar havmg a 011'- bearing block, the screw being adapted to 3101:? said type har 'in position upon its bsnrv tugs and gnlde the same.

-5. In a typewriting machine, the combination at a type bar hanger, a block" upon the hanger having a plurality of roundegl bearing surfaces," 21- type bar having a circnhu eye in which said bearing surfaces have :t working fit, and a SCI'BW for detachably connecting the block to the hanger, the said screw being also constructed to retain and gnigie the. type bar upon the bearing block In testimony wherepf I affix my signature in pTesence of two witnesses.
